Husband brought our cat into the vet today because he had an oozing wound near his rectum that turned out to be a ruptured anal gland. The vet said he’d need antibiotics and offered oral for 10 days or a single shot. She said the only difference was price. Husband opted for the shot since this cat is a biter. No sooner had he gotten our cat home than he noticed the cat panting, eyes got glassy and he ran and hid in our closet where he put his head against the wall and began to have a seizure. Husband scooped up his limp body and put him back in the carrier and drove him back to the vet.
Vet didn’t seem to believe the cat had a seizure and told us (I had just arrived from work) that she highly doubted the shot of Convenia she’d given our cat would’ve caused a seizure. I googled the drug and it states in multiple places that this drug is known to cause seizures as well as anaphylaxis, anemia and death amongst other things. This particular drug also stays in your pet’s system for 65 days so if they have an adverse reaction there’s little you can do about it.
My cat seems a bit more alert now than he was after the seizure but he’s clearly still not doing ok. I wish I would’ve been consulted or that husband would’ve been told more about convenia before anything was administered to our cat. This could’ve been avoided and I really didn’t appreciate the vet’s unconcerned attitude about the whole thing. If my cat dies from this shot heads will roll.
